RigMesh is a sketch-based modeling tool for the creation and editing of articulated 3D shapes. A skeleton is generated from a silhouette sketch, and a valid rig is maintained throughout the modeling process; skeleton, skin weights, and a closed surface mesh are computed in real-time.

Smooth Skinning Decomposition with Rigid Bones

This paper introduces the Smooth Skinning Decomposition with Rigid Bones (SSDR) that can effectively approximate the skin deformation of nearly articulated models as well as highly deformable models by a low number of rigid bones and a sparse, convex bone-vertex weight map.
